title: Postoperative surveillance of patients with carcinoma of the colon and rectum.
abstract: The early detection and management of recurrence following curative resection for colorectal carcinoma can prolong survival. However, at the present time there is no consensus on the appropriate follow-up protocol for such patients. This investigation was undertaken to determine which tests and procedures are most useful in detecting recurrence and the frequency with which they should be employed. Another purpose of this study was to identify those patients at high risk for recurrence. Sixty-five patients who underwent curative resection of adenocarcinoma of the colon and rectum were followed for at least two years or until recurrence. Thirty were classified as Duke's A carcinoma of the colon, 18 were Duke's B, and 17 were Duke's C. Mean follow-up was 44.9 months. The follow-up regimen consisted of clinical exam, liver function tests, carcinoembryonic antigen (CEA) level, and chest x-ray every three months for the first two years postoperatively and every six months thereafter, and colonoscopy or barium enema and proctoscopy every six months for the first two years postoperatively and every year thereafter. Seventeen patients (26%) had a recurrence; 24% per cent of these developed within one year, 65 per cent developed within two years, 82 per cent developed within three years, and 94 per cent developed within four years of resection. Recurrence was detected by CEA in eight patients, chest x-ray in five, endoscopy in three, and laparotomy for small-bowel obstruction in one patient.(ABSTRACT TRUNCATED AT 250 WORDS)
